Preface
Intergraph Computer Systems’ StudioZ SDI card provides a complete video solution, allowing
you to capture, edit, and play back real-time video and animated computer graphics. The
StudioZ SDI Card Hardware Guide contains information on setting up and using the card, and
on rebuilding system software used by the card.
StudioZ SDI combines Joint Photographic Experts Group (JPEG) compression/decompression
circuitry with serial digital interface (SDI, also known as DI) video on a single Peripheral
Component Interconnect (PCI) card. StudioZ SDI relies on your workstation’s audio
processor and Windows NT multimedia tools for audio capability.
StudioZ SDI audio/video operations allow you to:

StudioZ SDI is designed for use with audio and video editing software products that run under
the Windows NT operating system.
v
Capture video and audio to hard disk with or without video compression.
Play back audio and video from hard disk with or without video compression.
Compress and decompress images (via hardware) as part of the editing process.
Convert sequences of uncompressed still images to full-motion format for editing and
real-time playback.

1 Connecting to the StudioZ SDI Card
This chapter describes how to connect peripheral devices in a standard digital or analog video
and audio configuration to the StudioZ SDI card.
Overview
Peripheral devices such as video tape recorders (VTRs) and digital audio tape (DAT) drives
connected to your workstation let you capture and output video and audio material. The
StudioZ SDI card is your workstation’s interface to video peripheral devices. You can control
this equipment remotely with the application software installed on your workstation.
The StudioZ SDI card is installed in a Peripheral Component Interconnect (PCI) expansion
slot in your workstation. You can find the card and its connectors by looking at the expansion
slots at the back of the workstation.
If you need to replace the StudioZ SDI card, remove the existing card and install the new card
in the same location from which you removed the old one. See the documentation delivered
with your workstation for information on replacing expansion boards.

Cables
When selecting cables to use when connecting peripherals to a StudioZ SDI card, note the
following recommendations.
Cables
S-video or Y/C cables Use high-performance cables. Gold Series are commercially
Coax cables (BNC to BNC) Use high-quality 75 ohm coaxial cables. If needed, cables and
CAUTION Adapter use is a potential source of signal degradation. If you must use adapters, use only
high-quality, tight-fitting adapters.
Recommendations

adapters (BNC to RCA, etc.), are commercially available
through local audio/video suppliers and general electronics
suppliers.

Your workstation may also come with a machine control cable to connect between the system
and a VTR.
NOTE You should not replace the machine control cable with any other cable, but you can extend the
RS-422 end of the machine control cable with other cables if necessary.
Connections
Video input and output (I/O) are connected through connectors on the StudioZ SDI card. The
StudioZ SDI card includes 75-ohm BNC connectors for SDI and reference signal input, and
SDI and Composite output. A 4-pin mini-DIN port is included for S-video output.

Your workstation may also come with a machine control cable to connect between the system
and a VTR. If it does, you must connect the machine cable to the COM 1 port on your
workstation, and to the REMOTE IN port on the VTR.

Connecting a Video Monitor
C
Connect a video monitor to the StudioZ SDI card using the recommended cables. Place the
video monitor and your workstation’s computer monitor at least one foot apart to avoid
synchronization interference.
The following instructions are guidelines for connecting your equipment. See the video
monitor documentation for information on connecting cables to the monitor.
To connect a video monitor to the StudioZ SDI card:
Use one of the following methods:
u
Connect S-video (Y/C OUT) on the card to Line C IN (Y/C IN) on the video monitor.
u
Connect COMP OUT (composite video output) on the card to either Line A or Line B
Video IN (composite video input) on the video monitor.
u
Connect SDI OUT on the card to Component SDI IN on your video monitor (this is
applicable only if the video monitor has Component SDI IN and SDI OUT).
